1153689-18-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1153689-18-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,1,5,3,6,8 and 9 respectively; the second part has 2 digits, 1 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 1153689-18:
(9*1)+(8*1)+(7*5)+(6*3)+(5*6)+(4*8)+(3*9)+(2*1)+(1*8)=169
169 % 10 = 9
So 1153689-18-9 is a valid CAS Registry Number.

Cross coupling of polybromoiodobenzenes with some terminal alkynes
Shishkin,Tarasova,Khlevin
experimental part, p. 1323 - 1326 (2009/07/17)
Sonogashira reactions of pentabromoiodobenzene and tetrabromo-1,4- diiodobenzene with various terminal alkynes at 20°C in benzene resulted in selective replacement of the iodine atoms with formation of the corresponding alk-1-yn-1-yl-substituted polybromobenzenes.
